"What about Sun Na's parents? Have you been notified? Xu Sa pondered for a moment and spoke.

Zhou Hui nodded and replied, "I have already been notified by phone, and now the two of you are on their way here."

Xu Sa bowed his head, indicating that he understood.

Su Tong looked at Sun Na's information on the screen and was slightly puzzled, in addition to being similar to her various physical data, the three victims also had one thing in common, that is, they had well-behaved personalities and simple interpersonal relationships.

For such girls, their social circle will be relatively narrow and stable.

So how exactly did the murderer get in touch with the deceased?

"Zhou Hui, can you cross-compare the big data of the three victims?" Su Tong asked on a whim.

Since the murderer's choice of the murderer was premeditated, there must be something in common with the victim that they ignored.

"Yes, yes." Zhou Hui nodded hesitantly, "But the scope of big data is too broad, and I can only rely on a lot of information that already exists on the Internet." For example, medical records, or personnel files, etc., may not be too accurate. ”

Because of this, they rarely use the method of big data comparison.

"It doesn't matter. All I needed was to know if it was possible for the three victims to be sociable on a particular big data. "If they can compare something, it will be a good clue for them to catch the murderer.

"Zhou Hui, do as Su Tong says." Sitting on the head, Xu Sa knocked on the table with one hand and clapped the board.

"Yes!" As soon as he heard his leader's order, Zhou Hui immediately stood up straight and took over the task.

After that, everyone listed many common clues in the three cases, and although there were many more clues than before, they did not help much to catch the murderer.

For a while, everyone's investigation once again reached an impasse.

At three o'clock in the morning, everyone was still immersed in work.

In the corridor, Su Tong stood in front of the vending machine in a daze, not knowing what he was thinking.

At that moment, a large hand reached out from behind her and pressed straight on Black Coffee's case.

"Huh?" Su Tong came back to his senses violently, "I haven't chosen it yet!" ”

"I see you've been standing here for almost ten minutes, and I thought you didn't know what to choose." Xu Sa bent down to take out the drink that had fallen, "So I chose it for you." ”

"Who made you do it for yourself, and you know I don't like this instant coffee." Su Tong frowned, not knowing what Xu Sa was going to do.

"Really? I almost forgot. Xu Sa shrugged matter-of-factly, "Then this bottle is good for you to invite me." ”

"......" Su Tong glared at him speechlessly, "Can you be more cheeky?" ”

"Well, naturally, it depends on who it's right against." A flash of light flashed in Xu Sa's eyes, and he suddenly leaned down and approached Su Tong, "If it's you, I don't mind being thicker." ”

"Ahem, ahem!" Su Tong was so frightened that he coughed again and again, his face turned crimson, "You, you're all bored!" ”

Xu Sa's eyes narrowed and grinned, looking quite proud.

Su Tong intuitively felt that he was panicked by Xu Sa's staring, and hurriedly turned to leave, "I'm too lazy to tell you." ”

"Today's work is almost over, you can go back and rest." Xu Sa shouted at Su Tong's back in a happy mood, "At nine o'clock tomorrow morning, there will be an analysis meeting." ”

"You have to take care of it!" Su Tong replied without replying, and the pace of leaving sped up a little, making people look a little flustered.

Xu Sa shook his head amusedly.

Su Tong walked quickly all the way to the corridor, then slowly put down his steps, reached out and touched his hot cheek, feeling a little confused.

After so many things before, can she and Xu Sa really be together as if nothing happened?

Su Tong shook her head self-deprecatingly, at least after she had experienced so many things, she had no way to love someone as innocently but persistently as before.

"Kiri-chan?" As soon as Wen Yan came out of the office, he saw Su Tong standing in the corridor shaking his head vigorously, raised his eyebrows and responded, "What's wrong?" Isn't it uncomfortable? Do you want me to take you home first? I think today's work is about the same. ”

"No need, I'll just go back by myself." Su Tong was a little confused in his heart, so he refused without thinking too much, "It's so late, I'm afraid it's dawn when you send me back to my residence after you send me back." ”

"It's okay, I ......"

"It doesn't matter what it is." Before Wen Yan finished speaking, Su Tong waved his hand to interrupt him, "You've been tired for a day, and you're here to help us, if I tire you out, I'll be a sinner." With that, she left.

Su Tong said this, on the one hand, out of his selfish desire to be quiet alone, and on the other hand, he really didn't want Wen Yan to run back and forth.

She didn't know that the words she said unconsciously made the warm smile on Wen Yan's face gradually disappear.

Wen Yan stood in place, quietly looking at her back, and muttered for a long time, "You guys?"

Since what started, in Su Tong's heart, he was no longer the person standing by her side.

On this secondment, he was thinking of giving himself another chance no matter what......

But Su Tong's reaction when he mentioned the relationship between the two yesterday, and his reaction to subconsciously avoid his contact today, all made him feel dazzling.

I rubbed my hair a little frustratedly, and my heart was extremely depressed.

After working all day, for the sake of safety, Su Tong did not drive but directly took a taxi.

When she got home, she thought that her parents had already gone to sleep, and she deliberately took a light step.

As soon as I opened the door, I saw that the living room was brightly lit, and Feng Qingxue was sitting in the living room watching TV.

Hearing the movement at the door, she glanced over to this side, frowning casually, "Stinky girl, you're back so late!" ”

Su Tong's heart warmed, and he came up with a smile, "Well, the case in the bureau has been a bit tricky recently......

"Stop, stop." Feng Xueqing got up, "I'm not your father, so I'm not interested in listening to you say those psychopathic things." ”

She said as she headed into the kitchen, "I didn't say anything earlier when I came back so late, my soup has been heated several times, and it should be dry." ”

Su Tong followed along, and the aroma of food wafted out from the kitchen, "My favorite lotus root pork rib soup!" ”

"The nose is quite smart." Feng Xueqing was amused by her appearance, "You have been working overtime a lot lately, and everyone has lost weight, so I boiled some soup for you, drink it while it's hot." ”

"Mom!" Su Tong snorted, and his face was moved, "It's still good for you to treat me." ”

"Don't say pretty things there." Feng Xueqing nodded her forehead, "If you really want to thank me, get married and start a family early, I'm still waiting to hug my little grandson." ”
